Calamus

The Calamus (Acorus calamus) is a species in the genus Acorus. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical coniferous forests within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Colonial Oak Sedge

<em>Carex communis</em>, the colonial oak sedge, is a perennial sedge in the family Cyperaceae occurring in Sweden and the United States. This species has not been evaluated by the IUCN. It typically forms tufted clumps in shaded woodland habitats, particularly beneath deciduous oak and mixed hardwood forest canopies, where it tolerates low light conditions and well-drained acidic soils. Colonial oak sedge occupies grasslands, wetlands, temperate forests, and cultivated landscapes, suggesting moderate habitat breadth within its range. As a member of the large and ecologically diverse genus <em>Carex</em>, this species plays a role in woodland ground-layer communities, providing microhabitat structure for invertebrates and small mammals. Sedges in general are important components of cool temperate ecosystems, contributing to soil stabilisation and organic matter cycling. <em>Carex communis</em> is wind-pollinated and reproduces both vegetatively through rhizome extension and sexually through seed production. Biological traits of this species remain poorly documented in the scientific literature.
